Square meter (permeability) quick reference
| Square meter (permeability) | Darcy | Square micrometer | Millidarcy |
|---|---|---|---|
| 1 m² (k) | = 1013250000000 D | = 1000000000000 µm² | = 1.01325e+15 mD |
| 10 m² (k) | = 10132500000000 D | = 10000000000000 µm² | = 1.01325e+16 mD |
| 100 m² (k) | = 101325000000000 D | = 100000000000000 µm² | = 1.01325e+17 mD |
| 1000 m² (k) | = 1.01325e+15 D | = 1e+15 µm² | = 1.01325e+18 mD |
Where the square meter (permeability) fits
The next smaller permeability (porous media) unit is the square micrometer (µm²). 1 m² (k) = 1000000000000 µm², and 1 µm² = 1e-12 m² (k).
